All of the above, but of particular interest are those that involve the human subconscious.
The "answers" you receive from Ouija boards are provided by your own subconscious archives of information. Everything you have ever learned, experienced, dreamt, or sensed with any of your senses... it's all in there somewhere, even when you do not consciously realize it. A Ouija board can help unlock a few gates in your mind and retrieve that information. In a group, if everyone is serious about it than an answer could be drawn out from the combined knowledge and experience stored within the collective subconscious of all the participants. Despite the usefulness of this tactic, Ouija boards are usually inefficient and are more suited for occasional ceremonial purposes when seeking answers from within.
Meditation is another way to explore the subconscious, and is far more efficient and powerful than Ouija boards. There are also many health benefits to meditation. It strengthens willpower, helps one discipline their mind... but most importantly it can help us reach a temporary state of greatly heightened tranquility where all the mental noise and irrelevant surface thoughts can be banished, thus allowing us to traverse deeper into the realms within our own subconscious mind and explore the knowledge hidden within ourselves. Also... the mind after meditating becomes far better prepared to deal with any situation than it was before meditation.
Tarot cards also make powerful use of our subconscious, but in a different way. The cards depict human Nature and the human experience, so every single card applies to every single one of us in some way or another... and by using various card layouts or "spreads", there are infinite ways to interpret these cards subjectively as they apply to us as individuals. A "reading" invokes thoughts and feelings that are buried beneath the surface and can unlock doors deep within our subconscious and help us understand things about our current life that we may not have given much thought to before, if at all. If two people were to draw the same exact cards using the same exact spread, it would apply to each of them differently because of how different their personal history, life experiences, and subjective realities are. Combine this with religion/ spirituality and you have an incredibly powerful story in the cards that can reflect who you are and where you are going.
Supernatural? No. Witchcraft? Maybe, depending on how you look it. When you combine any powerful science (in this case, sciences of the mind) with a powerful spiritual/ religious system, you get "witchcraft".
Psychic?
Hell yes.
